Good choice for our hydraulic cylinder

1. With Rolling technology, the cylinder are straighter, the surface are harder and its quality are more durable.

2. All piston rod have to go through comprehensive processing: Heat treating Lathing GrindingPolishingHard chrome plating Polishing, this comprehensive processing make the cylinder harder, wearable and acid.

3. Using imported materials for seal kits.

4. The structure kits are made by high-strength Manganese plate

5. Advanced surface treatment:

A. Environmental automatically pipelined painting

B. Cleaning with automatic washing machine

C. Assembling in seal clean workshop

Quality Control
1. Cylinder products from purchased materials, processing, assembly, have strict quality control. ( we passed the certification of ISO/ TS 16949: 2009)

2. Automated cleaning equipment to ensure the cleanliness of fuel tank assembly.

3. Welding using CO2 arc welding and automatic girth welding, which ensure the welding
Quality of the seal parts

Selling Points of Our Hydraulic Telescopic Cylinder:
1. High precision, the outer and inner round of telescopic is processed by specific machine
2. Durable and corrosion, the Chrome thickness on the outer surface is up to 0.05mm
3. Stable quality, with imported seal material
4. The upper and lower support shaft is processed by overall forging to make its strength better.
5. In structure, our front lifting telescopic cylinder is mature and stable as European famous brands
6. In domestic market, most of the front lifting telescopic cylinder with 5390 stroke only have the maximum diameter of 180mm and minimum 100mm, but ours are 185mm and 110mm. So in theory, the lifting strength of our products upgrade 7%, and anti-flexural capacity increase 15%.
